C program to check a number is Armstrong or
not

This page has a
C program to check a number
is Armstrong or
not. The Armstrong number is an integer number.
Armstrong Number is also called as Narcissistic number or Pluperfect digital invariant.
Three digit Armstrong number must be equal to the sum of cubes of
all digits of the 3 digit
number. n-digits Armstrong number must be equal to the sum
of nth power of all digits of the n-digits number. For Example . .
. 153 and 1634 are Armstrong numbers. That is,
1*1*1*+5*5*5+3*3*3 = 153,
1*1*1*1+6*6*6*6+3*3*3*3+4*4*4*4=1634 are Armstrong
numbers. We can write the programs in many ways to find whether a
number belongs to Armstrong or not. In this webpage I have used
three techniques to find whether the given number
belongs to Armstrong or not. The below given C program
is used to check whether a
given number is Armstrong number or not. Kindly check out the
program to find whether the given number belongs to Armstrong
or not. The Armstrong or not program can be asked in
different ways for school and college going students.

I am
a ProfessorandHead of Department of
Computer Sciencein an
Arts and Science
College. I have designed this website to provide
solved example programs of different categories for all the school
and college going students to learn C language deeply, and to
practice Interview based Multiple Choice (Objective Type) questions
and answers.

Armstrong numbers can becheckd by Cprogram

The Armstrong is an integer
number, and it has no decimal point. It is clear that,
the n-digits Armstrong number must be equal to the sum
of nth power of all digits of the n-digits number. For Example . .
. the integer numbers such as 153 and 1634
are Armstrong numbers. The Armstrong
numbers can be checkd as 1*1*1 + 5*5*5 + 3*3*3 = 153,
1*1*1*1 + 6*6*6*6 + 3*3*3*3 + 4*4*4*4 = 1634. The Armstrong
numbers can be checkd by the above C program.
